Project Title

Development of laboratory methodologies for accurate simulation of engine tribochemistry. 

Project summary

Lubricant additive/material interactions in engine systems such as cam/follower or piston ring/liner are still not well understood, mainly due to the multidisciplinary nature of tribochemistry phenomena that define these interactions. As a result, there is still very little capability of accurately modelling these interactions limiting our ability to optimise them for achieving required friction and wear. The key task of this proposal is transferring the knowledge developed from the on-going ENTICE projects to practical experimental bench top tribotest methodologies for accurately simulating the tribochemistry processes that occur in IC engine systems.
